KB5068400 is a High security update for Microsoft SQL Server 2017 for x64-base, released 2025-11-11. It closes 1 CVE with a maximum CVSS of 8.8. It is the fourth largest of the 18 updates Microsoft shipped that month, by CVEs closed.
Update summary
Fixes 1 CVE. Most severe CVSS 8.8 (High). EPSS exploit probability up to 1.1%. Among the lower half of tracked Microsoft updates by EPSS exploit probability.
A newer security update for Microsoft SQL Server 2017 for x64-based Systems (GDR) has shipped since this one: KB5101346 (2026-07-14). For cumulative update families the newer package includes these fixes, so installing that one is usually the shorter path. Verify against your own update rings before you skip this package.
KB5068400 patches CVE-2025-59499, a High severity flaw (CVSS 8.8) affecting the GDR branches of SQL Server 2016 Service Pack 3, 2017, and 2019 on x64 systems. Exposure is limited to organizations still running these older SQL Server versions, and the CVSS of 8.8 combined with a low EPSS of 1 percent suggests exploitation is credible but not yet observed in the wild. It is not in CISA KEV and not ransomware-linked, so this is a schedule-and-patch item rather than an emergency.
Do this: Identify any SQL Server 2016 SP3, 2017, or 2019 x64 instances on the GDR servicing branch and apply KB5068400 during your next maintenance window.
